关于知识表示的讨论

知识表示是人工智能（ＡＩ）研究中基本问题之一,对ＡＩ来说,知识表示的研究分成两个层次：（２）知识表示方法的研究,（２）表示观的研究,首先,本文在总结各种表示方法的基础上,提出了一种“知识表示体系树”,以观察ＡＩ研究的发展趋势,其次,文中收集了目前ＡＩ学界对这个问题讨论了各种主张,并将其归纳为评论论、本体论及知识工程等三类对表示的观点;最后,还讨论了ＡＩ一些研究分支与表示的关系。

DISCUSSIONS ON KNOWLEDGE RERESENTATION

Knowledge representation is one of the fundamental issues in Artificial Intelligence (AI). There are two hierarchies in the research of this issue: (1) knowledge representation scheme; (2)scientific view of knowledge representation.Based on an investigation of various kinds of knowledge representation,an "Architecture Tree" of knowledge representation is presented in this paper,which implies the future development of AI. Then,a variety of viewpoints concerning knowledge representation were summed up into three views, i. e., the Epistemological view,the Ontological view,and the Knowledge Engineering view. The paper finally discusses the relationship between knowledge representation and some of the branches of AI.
